Cannot add new users into Dynamics Trial

Hi,

For some strange reason, i cannot add users into my Dynamics 365 Trial.

We want to do some testing on this program before we rent it (presuming it works well) but as the Admin, i am the only one who can login to it.

I have added the trial edition, selected a handful of users and assigned licenses to them inside 365 admin portal.

If they try to then select Dynamics from the home page of their portal.office.com login, no sales or other icons appear. If i give them a link manually they are denied access, because of security.

If i login into Dynamics and go to settings, security, and add users, i only see my username only, and a bunch of demo accounts in other sections. The new button only points me into the license area, but i have already done that part.

I ask my users to try other browsers, no change.

I am stuck.
